Abstract
808 nm QCW bars were fabricated and mounted with hard solder technology onto H-mounts and G-stacks. At room temperature, reliable operation has been demonstrated at 400W at 400A per single 1-cm bar and for a G-stack at 3kW at around 300A. High temperature reliable operation has been demonstrated for both devices up to 95°C. Both types of devices were tested at various pulse widths and duty cycles. Both optical power and wavelength dependencies on the various conditions have been studied.
